MACHINE FOR USE IN THE K ANUFACTURE OF SHOES.

Application filed July 25,

This invention relates to the manufacture of shoes, and is hereinexemplified in its application to the molding of the toe portion ofupper materials to give them substantially the shape which they are tohave in the finished shoe. It will be recognized, however, that in manyof its important aspects the invention is not limited to the shaping ofthe toe portion of upper materials, nor to the shaping of uppers asdistinct from other shoe parts, and that in still other aspects the1nvention is not limited to molding in the treatment of uppers or othershoe materials.

Among its objects the invention has in view important economies in shoemanufacture and uniform excellence in the quality of the product. Evenin the present comparatively advanced stage of development of theshoemaking art, many operations depend for success upon the exercise ofgreat skill and judgment by the workmen, thus entailing a high laborcost, and this is conspicuously true of the shaping of the uppermaterials. In shaping the toes of uppers, for example, much care andskill are needed, not only to conform the upper closely to thecharacteristically irregular curvature of the last or other shoe form,but also to gather and shape the marginal portion of the materialsmoothly and uniformly as required for the appearance of the shoe andfor successful results in subsequent manufacturing operations, and toestablish correctly and in accordance with a predetermined standard thelines of the upper characteristic of the given style of shoe. Even withthe exercise of the greatest care and skill obtainable at a high laborcost, the difficult and critical operations involved in upper shapingoften fall short of that degree of accuracy and uniformity which isrecognized as essential for the best shoemaking.

In View of the above mentioned and other conditions and with the generalobject above set forth, the present invention, in its illustrativeembodiment, provides a novel machine organization designed forstandardization in the shaping of upper materials. A very importantfeature of the organization, which contributes directly to uniformity ofthe product and to the elimination of the need for a high degree ofskill on the part of the workman, consists in the combination of 1921.Serial No. 487,384

means for operating upon the material and means for jigging the materialto position it relativel to the means which operates upon it. T at is,as herein exemplified, there is provided means for insurin by engagementwith positioning surfaces ormed on the upper in predetermined relationto a characteristic thereof the proper position of the upper in relationto the upper-shaping means in respect to such movement as might affectthe accuracy of the shape imparted to the upper by said means. Themachine herein shown comprises means for utilizing jig holes formed inthe marginal portion of the toe of the upper to position the upper inpredetermined relation to the upper shaping means. The means illustratedfor use in jigging the material, in which also an important feature ofnovelty is to be recognized, comprises a presenter adapted to engage thework and move it into predetermined relation to the operating means andthen to Withdraw from the work. Still other important features are to berecognized in an organization of means for jigging the material andmeans for operating upon the material in a manner not only to effect therequired shaping operation but also to insure effective control of thematerial to maintain it in its jigged relation to the operating means.In the machine illustrated the desired results are secured by clampingthe margin of the upper in the position determined by the jigging, andfurther in the course of the upper shaping operation by clamping theintermediate portion of the toe of the upper against the form, andsubsequently clamping the upper also about the end of the form while itsmargin is shaped over the form, thus maintaining an effective control ofthe jigged upper by clamping pressure in one or more locationsthroughout the upper shaping operation.

In another aspect the invention presents various features of novelty inan organization of means for shaping the upper materials, comprising anovel construction and arrangement of means for shaping the materialabout a form and for molding its margin inwardly over the form, themachine illustrated having means for molding the margin of the upper toproduce inturned and upstanding portions adapted to conformsubstantially to the feather and the rib of a welt shoe insole. Amongits other features, the invention provides novel means for clamping andcontrolling the margin of the upper an novel means for wiping the upperheightwise of the form and for clamping it about the form. As applied toan organization wherein the upper is permitted to set until it hasacquired permanently the shape imparted to it, the invention furtherprovides for relaxing the clamping pressure about the lateral peripheryof the form to avoid marking the upper by the heavy forming pressure.\Vhile the invention, in many of its aspects, is not dependent forutility nor limited to the shaping of uppers oil the last, the machineillustrated is designed for molding the toes of u pers to give themsubstantially the shape w ich they are to have in the finished shoesbefore the uppers are mounted on their lasts. Aside from the economiesobviously involved in the elimination of the skill and care heretoforerequired in toe lasting, and the other advantages hereinbeforediscussed, this efi'ects also a saving in lasts and other equipment dueto reduction of the time the shoes must remain upon their lasts, and byreason of the heavy molding pressure to which the uppers may besub]ected oil' the last contributes as well to permanence of shape inthe finished shoes.

Still another feature of the invention is to be recognized in a novelorganization of means for shaping the work and means for trimming it,the machine illustrated having a trimmer which is movable in apredetermined path to trim the upstanding margin of the up er round thetoe while the upper is under mo ding pressure. In an organization suchas illustrated, in which the upper is jigged to position it inpredetermined relation to the upper shapin means, the provision oftrimming means re atively to which the upper is also ji ged insures ahigh degree of accuracy in t e trimming operation. In connection withmolding the end of the upper oif the last, a further important advantagein trimming the margin, as required for ex ample rior to the inseamsewing operation, while t e upper is under molding pressure, arises fromthe fact that the upper is then under better control for the trimmingoperation than at any subsequent stage in the manufacture of the shoeprior to the sewing of the inseam.

The features of the invention hereinabove discussed, as well as otherfeatures involved in various details of construction and combinations ofparts not specifically referred to in the above general discussion, willnow be more particularly set forth in connection with the aceompanyindrawings and pointed out in the claims. hile the invention is hereinillustrated in its application to welt shoe work, it will be recognizedthat in many of its aspects the invention is not limited to welt shoemanufacture.

\Vhen the end portion of an upper has been shaped about the form ashereinafter described, it should preferably be permitted to set, toinsure that when removed from the form it will permanentl retain itsmolded shape. To assist in hol ing the end of the upper in shape astiffener may be placed between the leather or cloth forming the shoeupper' proper and the lining. There are various kinds of shoe endstifi'eners which may be advantageously em loyed, but in the presentexemplification o the invention a shoe end stiffener that may berendered pliable by heat or moisture is employed and the illustratedmachine is more especially adapted for the treatment of the ends of shoeuppers having stifieners which are rendered pliable by heat.

The machine shown is of the twin type, one of the two mechanisms beingadapted to treat the uppers of right shoes and the other those of leftshoes, this arrangement also ermitting one upper to set to the moldeshape while the other is bein placed in the machine and subjected to moling pressure. Except as modified for the treatment of right and leftshoes, the two mechanisms are similar in construction and mode ofoperation, so that a description of one will suffice for both.

The machine frame is of suitable character to support the operatingparts, and as shown comprises the side frame members 1 upon which ismounted a top or table portion 2. Extending between the side members 1is the main driving shaft 3 which may be appropriately drivencontinuously from any suitable source of power. Preferably the drivingshaft 3 is driven by an electric motor 4, operatively associated withtransmission shaft 5 connected to the driving shaft 3 through a suitabletrain of gearing which is typified at 6 (Fig. The train of gearing maybe of any appropriate character, the essential in this respect beingthat rotative movement of the transmission shaft 5 may be transmitted torotate the driving shaft 3.

Extending transversely of the driving shaft 3 and mounted in suitablebearings 7 and 8 carried by the machine frame is the clutch shaft 9driven through a train of mechanism from the driving shaft 3. In thepresent instance the driving shaft 3 has secured thereto a spiral gear10 which meshes with a spiral "car 11 formed on or secured to a clutchmember 12 loosely mounted on the clutch shaft 9. A clutch member 13 issplined to the clutch shaft 9 and is under the control of the workmanwho may, at will, engage the clutch members 12 and 13, or disengagethem, and thereby either start or stop the retation of the clutch shaft.To this end the clutch member 13 is provided with a grooved portion 14which is embraced by the end portion of an arm 15, Fig. 2, mounted forsliding movement on a guide or rod 16. Connected to the hub portion ofthe arm 15 is a rod 17 which is connected to a hand lever 18 mounted ona supporting rod 19 held in the machine frame. In the construction shownthe hand lever 18 has a downwardlyextending portion 20 which isconnected by a link 21 to the shifting rod 17, the construction beingsuch that by manipulation of the hand lever 18 the workman may throw theclutch members 12 and 13 into or out of engagement. The hand lever 18may be held in the position to which it is moved by means of a bracketor arm 22 having notched portions such as 23, in which the hand levermay catch at its extreme positions. The controlling means thus providedis adapted for use to stop the mac ine at any point in its cycle independently of the normal starting and stopping means hereinafterdescribed.

Secured to the clutch shaft 9 is the worm 24, Figs. 1 and 2, which isengaged with a worm wheel 25 mounted on a hub 26, Fi 2. Between the sideframe members exten s a cam-carryin rod or shaft 27 on which the hub 26of t e worm wheel 25 is rotatably mounted. At each side of the hub 26the rod or shaft 27 carries a sleeve 28 on which cams are mounted foreffecting movements of the operating parts of the corresponding half ofthe machine in the formation of the ends of shoe uppers into their finalshape.

The sleeves 28 are independent, and either one may be selectivelyconnected to the hub of the worm wheel 25 for rotative movementtherewith by clutch mechanism of any preferred type. In the constructionshown each of the sleeves 28 is provided with a clutch pin 29 having aclutching portion 30 adapted to be engaged with and disengaged from ahardened metal ring 31, mounted fast in a Hill side portion of the hub26, as more clearly indicated in Fig. 2. Each of the clutch pins 29 isprovided with an outwardly-extending pin 32 which engages a ring 33mounted on the corresponding sleeve 28. Each of the rings 33 is normallyunder the influence of a spring 34 tending to rotate the clutch pin 29in a direction to engage the clutch pin with the ring 31 in the hub 26of the worm wheel to effect rotative movement of the sleeve. Each of therings 33 is provided with two shoulders 35 (Fig. 1) which are adapted tocontact with a clutch disengaging member 36 under control of theworkman. Since there are twin mechanisms. each of which is to beselectively operated, the clutch engaging and disengaging mechanisms maybe similar, and a description of one will sufties for both. In thepresent instance the member 36 is mounted for rocking movement upon thesupport 19. Fig. 1, and has a. downwardly-extending portion 37 which isnormally under the influence of a spring 38 tending to hold the member36 in osition for engagement with one of the s oulders It is desirablethat after the workman has tripped the clutch disengaging member 36,such member shall move back into position for engagement with thesucceeding shoulder 35, without further attention on the part of theworkman, and bring the connected sleeve 28 to rest. To this end thedownwardly-extending portion 37 has pivotaily mounted thereon at 39 atrip block 40 normally held in the position indicated in Fig. 1 by aspring 41. A treadle 42 is pivotally mounted at 43, and has an endportion 44 adapted to engage and ride over the end of the block 40 whenthe treadle is depressed; and a spring 45 returns the treadle to itsnormal position, as indicated in Fig. 1. when the foot of the workman isremoved. Should the workman, however, by oversight, fail to remove hisfoot from the treadle, the trip 40 will tilt after the end 44 of thetreadle has passed its operating end, and permit the clutch-disengagingmember 36 to return to clutch-disengaging position.

Pivotally mounted at each side of the machine for swinging movementabout a cen tre 46 on the top of the machine frame, Fig. 1. is a formcarrier 47 having connected thereto at 48 an operating member 49 whichextends downwardly and is under control of a cam mechanism on thecorresponding sleeve 28. In the construction shown the operating member49 has a head 50 through which passes the upper end of a rod 51connected at 52 to an arm 53 mounted on a rod 54 supported at the rearof the machine frame. Extending from the arm 53 is a stud or roll 55,Figs. 1 and 5, which lies within a cam groove 56 formed on a cam 57carried by the sleeve 28.

When the upper has been laid about the form by the downward movementthereof, and prior to the inwiping movement of the wipers, as willhereinafter more fully appear, it is desirable that the form continueits downward movement far enough to permit the wipers to wipe the upperover the margin-a1 edge portion of the form without inuring the upper,and thereafter to cause the form to press the inturned edge portion ofthe upper yieldingly against the lower surface of the wipers, and thecam 56 is appropriately shaped to effect these results. To effect theupward yielding pressure of the form against the inturned upper, aspring 58 is interposed between a collar 59 on the rod 51, Fig. 1, andthe head 50, the upper end of the rod 51 having connected thereto thecollars 60, and the construction being such that after the form has beenlowered to permit the inwiping movement of the wipers, the rod 51 willbe raised by the cam to compress the spring 58 and yieldingly uplift theform against the overwiped portion of the upper.

Mounted upon the head portion 2 of the machine, beneath the cover plates61, are wiper holders 62 which carry wipers 63. Guiding slots 64 formedin the wiper holders are engaged by pins 65 passing through the coverplate to direct the movement of the wipers. Each of the holders 62 isconnected by a link 66, Fig. 3, to a crosshead 67 having arearwardly-extending portion 68 (Fig. 1) connected to toggle members 69and 70 jointed together at 71. The toggle member 70, Fig. 1, ispivotally connected to a yielding abutment which may be convenientlyformed by a rod 72 having collars 73 between which and the machine frame2 is interposed a spring 74, the construction being such that when thetoggle is straightened as indicated in Fig. 1, the wiper holders and thewipers will be moved to overwiping position with provision for yield.Adjustable stops preferably in the form of threaded nuts 75 limit themovement of the rod 72 under the impulse of the spring 74.

Connected to the toggle at the joint 71 is the toggle-operating meanswhich, in the construction shown, comprises a head 7 6 and an adjustabletoggle operating rod 77, Fig. 1. The lower end of the operating rod 7 7is connected at 7 8 to an arm 7 9 pivotally supported by the rod 19. Toimpart ope rative movement to the rod 7 7 and the wipers. the arm 79carries a stud or roll 80, best shown in Fig. 4. which lies in a ramgroove 81 formed in the side of a cam wheel 82, Figs. 2 and 4. It may bedesirable in some cases to limit the breaking movement of the toggle,which may be appropriately efiected by means of a stop 83, Fig. 1,adjustably mounted in the head 76 and adapted to engage a. projection 84secured to the top portion 2 of the frame.

For purposes of the present invention there PHI is provided means forjigging the upper to position it in predetermined relation to the formby engagement with the upper In jig holes formed in its margin atopposite sides of the toe in redcter'mined relation to a characteristicthe upper. The predetermined position of the end of the upper relativelyto the form when the upper is placed in the machine is secured, in theconstruction shown, by the aid of a presenter which is constructed andarranged to support the upper in inverted position. The wipers 63 areeach provided with co-operating positioning means which, in the presentinstance, are in form of slots the walls of which are adapted to be enga"ed by portions of the presenter to position the upper. The presentermay be variously constructed, but .as shown it comprises the two sidearms 86 which are arranged a suflicient distance apart to permit theentrance of a portion of the upper. At the forward end of each arm thepresenter has a projection or upper engaging portion which, in thepresent instance, comprises a pin 87, Fig. 12, the ends of the pinsbeing reduced in diameter for engagement in the ji holes in the upper.The two portions 86 o the presenter may be extended to form a handleportion 88, Fig. 23, at the rear of the upper as a convenient means formanipulating the presenter to place the upper in the machine. Thepresenter may be constructed of resilient metal to adapt it for uppersof different shapes and sizes.

The upper which is to be placed in the machine is provided withpositioning surfaces which are preferably formed by jig holes 89 made inthe upper at separated points located at predetermined distances from adatum point, as for instance, the back centre line of the upper as at90, Fig. 23, the construction being such that if all shoe uppers of thesame size and style are provided, with similarly located jig holes andthe uppers are presented to the form by reference to such ig holes, thelength lateral position, and angularity of the'molded ends of all theuppers of the series will be identical. Where the end of the upper isprovided with a tip 91 which is secured to the vamp 92 by fastenings, asindicated in Fig. 22, the jig holes 89 may be formed on the vamp atpredetermined distances from the back centre, and on the tip atpredetermined distances from the front centre, such that when the tipand the vamp are assembled together, and the jig holes of the vamp andthe tip are brought into matching relation, the length, lateralposition, and angularity of the tip with reference to the vamp will bedetermined. As indicated in Fig. 22, the jig holes 89 may advantageouslybe formed between the lines of stitches which secure the tip to thevamp.

In presenting a shoe upper to the machine for treatment, the jig holes89 in the end of the u per are engaged by the projecting pins 87 0? thepresenter, and the main portion of the upper at 93 will extend betweenand be supported by the side members of the presenter substantially inthe position indicated in Fi 23. With the upper in predeterminedrelation to the resenter, the workman has simply to move is e presenterto bring the pins 87 thereof into the positioning slots 85 of the wipersuntil the pins engage the locking end portions 94 of the slots, whichthereu on automatically determine the relation 0 the presenter andwipers, and consequently the position of the outspread upper withrelation to the form. In order to assist in guiding the presenter andits supported upper into proper relation to the wipers, there areprovided on the ins 87, in the construction herein shown, le ges 95which are spaced below the upper supporting shoulders on the pins adistance substantially equal to the thickness of the wipers and arearranged to engage the lower surface of the wipers as the pins are movedinwardly along the slots 85. The relation of the presenter and the upperto the wipers when the upper is in position for the molding operation isindicated in Fig. 11.

When the end of the shoe upper has been placed in predetermined positionwith relation to the form, as above described, it is desirable that theupper be freed from the presenter and clamped in position for treatmentby the machine. In the construction shown the outspread upper is heldupon the top surface of the wipers by clamps, which as they are moved tooperative or clamping osition, assist in disengagin the presenter mm theupper. The action 0% the clamps is preferably made yielding, so that themarginal portion of the upper may be partially withdrawn from betweenthe clamps and the wipers as the upper is laid about the form.

The clamps for holding the marginal portion of the upper upon the wipersmay be in the form of plates 96, Figs. 3, 11, 13 and 15, arranged toco-operate respectively with the different wipers. While in some casesit is not necessary, yet it is preferable to form the clamping plates 96so that when they are in clamping position they will exert asubstantially continuous clamping action round the end portion of theupper which is to be molded; and since the two clamping members on eachof the twin machines are identical, a description of one will besutiicient.

Secured to and movable with the wiper holder 62 is the stud 97, Figs. 3and 11, which passes through an elongated slot 98, Fig. 3, formed in thecover plate 61. If desired, a slide 99 may be carried by the stud 97 tocover the elongated slot 98 more orless as the wiper plate and the studare moved relatively to the cover plate. Connected to the stud 97 is theclamp carrying arm 100 which has an elongated slot 101 engaging a crosspin carried by the stud. Pivotally mounted on the end of the arm 100 at102, so as to maintain at all times a substantially parallel relation tothe plane of the wipers, is the clamping plate 96. A link 103 extendsbetween the arm 100 and a stud 104 mounted on the wiper holder, and isnormally in an inclined position when the clamp carrying arm 100 ISraised, as indicated in Fig. 11. When, however, the clamp carrying arm100 is depressed, as will be presently described, the link 103 serves tomove the clamp 96 inwardly and bring it into closer relation to the edgeportion of the wiper, with which it co-operates. An advanta e in thusengaging the margin of the upper by the clamps close to the edges of thewipers is that uppers may be cut as small as is consistent with otheroperations of the molding mechanism without interfering with the properfunction of theclamps. By reference to Fig. 13 it will be noted thatwhen the clamps are in clamping osition the links 103 are still inclinedto the horizontal, and consequently the subsequent withdrawing movementof the clamps is outward from the edge of the form as well as upward.This insures that the clamps will. not interfere with the margin of theupper which may in the final retracting movement of the clamps projectupwardly inside of the inner edgesof the clamp members.

The clam -carrying arm 100 is preferably constructed with two sidemembers, as indicated in Fig. 3, and through the space separating theside members extends a stud 105 which is secured to the wiper holder 62.Between the two side members 100 constituting the clam -carrying arm, isthe sleeve 106, Fig. 21, aving the upper and lower flanges 107 and 108,the construction being such that should the sleeve 106 be raised orlowered, it will operate upon the clamp carrying arm to similarly movethe clamp. The sleeve 106 has an upwardly extending portion 109 providedwith slots 110 into which project the ends of pins 111, Fig. 20. Thepins 111 are carried by a sliding member 112 to the upper end portion ofwhich is adjustably connected a cap piece 113. Mounted in a socketedportion of the stud 105 is a spring 114, the normal tendency of which isto lift the sleeve 106 and to correspondingly lift the associated clampcarrying arm 100. Between the lower end of the cap piece 113 and the topof the sleeve portion 109 is a spring 115 which, when compressed by thedownward movement of the cap piece 113, yieldingly forces the sleeve 106downwardly to carry the clamp into clamping 081161011.

T e present invention provides means for automatically operating theclamps to the end that when the presenter has moved the end of the shoeupper into predetermined position relatively to the form, the clamps maybe operated to clamp the marginal rtion of the outspread upper and tomove t e presenter in a direction to disengage it from the upper.Clamp-operating arms 116 are pivotally mounted on the top of the machineframe at 117, Figs. 1 and 3. In the present instance, the operating arms116 are carried by a sleeve 118 which is mounted for rocking movementabout the axis 117 and has a rearwardly-extending arm 119, Figs. 1 and3, to which is connected one end of an operating rod 120, the lower endof which is connected at 121 to an arm 122 mounted for rocking movementon the support 54, Figs. 1 and 4. The arm 122 has a pin or roll 123which is engaged by a cam formation 124 on the peripheral portion of thecam wheel 82, Fig. 4, the construction bein such that upon rotation ofthe cam the clamps will be moved to and from operative position. Aspring 125 interposed between a stop 126 and a collar 127 on the rod 120serves to hold the roll 123 in engagement with its operating cam. Tofacilitate adjustment of the movement of the clam s, the rod 120 may beadjustable in lengt as by a turnbuckle, as shown in Fi 1.

Each operating arm 116, Fig. 3, has a s otted end portion 128 throughWlllCh extends the sliding member or sleeve 112 which, as hcreinbcforedescribed, compresses the spring 115, Fig. 20, when the member or sleeve112 is depressed, to effect a yielding clamping action of the clamp. Asindicated in the sectional illustration of Fig. 20, the operating arm116 normally rests upon the pin carrying lugs which project outwardlyfrom the sleeve 112 and when the operating arm 116 is moved downwardly,it carries with it the sleeve 112, compresses the spring 115, andefi'ects the downward, yielding clamping action of the clamp upon theupper. To insure the lifting movement of the clamp, the cap piece 113 mahave associated therewith a collar 129, Fig. 20, provided with anoutwardly extended portion 130 adapted to be engaged by the operatingarm 116 as the latter is raised through the train of, mechanismhereinbefore described. Adjustment of the cap piece 113 ma be effectedto vary the tension of the spring. While the means described foroperating the clam s is found to be a good, practical form of t isfeature of the invention, yet variations may be made therein, it beingdesirable, however, that the clamps, as shown, be automatically operatedto effect the clamping action u on the marginal portion of the upper anto release it at predetermined times, as will be more fully described. 1

Where the clamps, as in the construction shown, comprise plates such as96, which extend continuously for some distance about the end portion ofthe shoe upper, it is sometimes desirable to connect the clam s at theirends to the operating arms, as we 1 as at an neoaase intermediate ointsuch as hereinbefore described. To this end each operatin arm 116carries a sleeve 131, Fig. 15, whic is confined to the arm 116 by a stopscrew 132. Within the sleeve 131 is a plunger 133 upon which rests thelower end of a spring 134, the tension of which may be varied by athreaded adjusting cap 135. Against the plunger 133 rests the upper endof a pressure-transmitting member 136, the lower end of which isconnected by a ball and socket joint 137 to the outer end portion of theclamp 96. The construction is such that when the operating arm 116 ismoved downwardly to e ect the clamping action upon the marginal portionof the u er, the outer end portion of the clamp wil e moved downwardlyunder the yielding action of the sprin 134 and insure, for example, asubstantia ly equal clamping action on the marginal portion of the upperthroughout the clamping surface of the clamp. On the other hand, it maybe desired on some work to clamp the margin of the upper harder at somepoints than at others, for example to apply greater clamping pressure atthe opposite sides of the form, at or near the location of the ti seam,than round the end of the form. his may be done in the constructionshown b the independent means provided for ad uSting the differentsprings 115 and 134.

When the form and the margin controlling means are relatively moved tolay the upper about the form, the clamps have a suflicient retardingaction upon the withdrawal of the upper to insure its being drawnclosely over the form. When, however, the wipers are operated to wipethe upper inwardly, and thus to lay the marginal portion of the upperover the bottom of the form, if the clamping pressure of the clamps werestill maintained on the upper, or if the full force of such ressure weremaintained, the wipers would liable to injure or tear the up er,especially with some kinds of upper stoch. Therefore the invention, inits illustrated embodiment, provides such an arrangement of wipers andclamps and their operating mechanism that during the time the upper isbeing laid about the form, the clamps will yieldingly retard thewithdrawal of the upper; but before the wipers receive any substantialinward movement to wipe the marginal portion of the upper over thebottom of the form, the clamps will be caused by the cam 124 to releasethe upper substantially from clamping pressure. By reference to Fig. 17however, it will be seen that the clamps do not receive at once theirfull withdrawing movement, but remain in position to bend the margin ofthe upper outwardly over the wipers While the wipers are closing, thuscontributing to effectiveness of the wipers in wiping the upper smoothlyand tightly inward over the form.

Substantially accurate conformation of the upper with the surface of theform is essentla to insure uniformity in the shape and condition of aline of shoe uppers molded about the form; and while the action of theclamps insures to a degree that the upper will be laid properly aboutthe form, the invention further provides for working the upperheightwise of the form by pressure against the u per about the end ofthe form. This may t be effected by subjecting the portions of the upperwhich are about the lateral periphery ot the form to the rubbing orwiping pressure of an embracing clamp or band, though other forms ofmeans may suggest themselves within the scope of this feature of theinvention. In the present instance band carriers 138 are uided formovement in slots 139 formed in t e head portion 2 of the machine frame.The band carriers 138 carry the band support or backing 140, Fig. 6,comprising opposite side portions to which the band 141 is secured. Theband may be of leather or other material suitable for the urpose. Theband carriers are connected or pivotal swinging movement about an axis142. Each of the band carriers 138 is under the influence of a springwhich normally tends to separate the band carriers as indicated in Fig.6. In the present instance the band carriers are provided with pins 143to each of which is connected one end of a spring 144, the other endbeing secured at 145 to a fixed point in the machine, the constructionbeing such that the springs 144 normally tend to open the end band.

Each of the end band carriers 138 has associated therewith an adjustingscrew 146, Fig. 6, the rear end portion of which bears upon a slidingblock or plunger 147 mounted for sliding movement in the head frame 2.Extending backwardly from the blocks 147 are links 148, the rear endportions of which are connected to the upper end portions of arms 149,Figs. 6 and 10, mounted upon a rock shaft 150. Extending from the rockshaft is an operating arm 151, Figs. land 10, to which is connected anoperating rod 152, Figs. 1 and 4, the lower end portion of which is connected at 153 to an arm 154 mounted for oscillating movement upon thesupport 19 and carrying at its outer end a cam follower or roll 155which projects within a. cam groove 156 formed in the face of the cam82, the construction being such that as the cam rotates, the end band,which is indicated as a toe band, will be opened and closed as will morefully appear.

Since the end portions of shoe uppers will vary in size and shape inaccordance with the size and style of shoes, provision is made in thepresent invention for accommodating the toe band to such variations. Inthe construction shown the pivotal connection 142, Fig. 6, between theend band carriers, is carried by a link 157 which in the closing andopening of the band slides in a slot formed in the head frame of themachine and is ivotally connected at 158 to an operating ever 159pivoted at 160 to a sliding carrier 161 which is guided by a pin andslot guiding means 162 for endwise movement. The sliding carrier 161 ispivotally connected at 163, Fig. 10, to one of the arms 149 whichoperate the end band carriers, so that the band will be moved lengthwiseas well as opened or closed laterallv. The end 164 of the lever 159 isconnected to an adjusting rod 165 which has at its front end a threadedconnection 166 with an adjusting nut 167. A spring 168 is interposedbetween a collar 169 on the adjusting rod 165 and the top frame 2 of themachine, the construction being such that the spring 168 normally forcesthe end 164 of the lever 159 rearwardly to position the pivotalconnection 142 of the end band carriers, and by adjustment of the stem165 the initial position of this pivotal connection may be varied.Corresponding adjustments of the band carriers about the axis 142 may beeffected by manipulating the screws 146. By these different means theband may be positioned to co-operate properly with different shapes andsizes of forms over which uppers are to be molded. By reference to Fig.6 it will be noted that the link 157 is permitted to have a limitedlateral movement in the slot through which it extends, and provision isthus afforded for bodily lateral movement of the band in one directionor the other to accommodate itself to the form as the latter is forceddownwardly within it. It will be evident that the band carriers areunyieldingly positioned against lateral swinging movement and againstmovement lengthwise of the form in response to the forming pressure.thus maintaining the band in unvary ing contour throughout the upwipingoperation.

The form 170, Figs. 7, 8 and 9, has a forming surface correspondingsubstantially to the shape that the shoe upper is to have in thefinished shoe; and on its bottom face a marginal edge shoulder 171extending inwardly a short distance from the outer edge of-the form. Atthe inner portion of the shoulder 171 the form is provided with a raisedportion or shoulder 172, the construction being such that when the upperis wiped in by the wipers it will be laid upon the shoulder 171 of theform to provide an inwardly extending shoulder on the upper, and theedge portion of the upper will be compressed or molded about the centralraised portion of the form to provide an upstanding marginal flange.

In the present instance the form 170 is mounted upon the form carrier 47and is preferably detachably connected thereto. As shoivn, the form hasin its bottom, which is uppermost, a hollowed portion 173, Figs.

7 to 9, and an inwardly-extending flange 174 beneath which is adapted toen a collar 175 formed on the lower end of a orm-securing rod or stem176. The n per end portion of the securing rod is provi ed with a screwthread 177, which is engaged by an adjusting nut 178. The rod 176extends through a bushing 179, the lower end portion of which is formedwitha shoulder 180 adapted to engage the top surface of the flan e 174extend- 1ng inward y in the recess 17 3 o the form, the constructionbeing such that when the flan e 174 is placedbetween the collar 175 andthe shoulder 180 of the bushing, and the ad'usting nut 178 ismanipulated, the form will be secured in operative position on the formcarrier. The described detachable connection between the form and theform carrier resents a convenient and ready means for e ecting a chan ein forms, but the particular means may varied.

As the u p er is molded about the form, the latter is su jected to anendwise pressure outwardly or toward the heel end of the upper. Thepresent invention provides additional means for counteractin suchpressure against the form by a brace adjustably connected to the formcarrier. In the construction shown a brace or abutment 181, Figs. 1 and7, is pivotally mounted at 182 between arms 183 on the form carrier 47.The lower end portion of the brace 181 is provided with a lug 184, theinner face of which, when the brace is in bracing position, bearsagainst the front end face 185 of the form. An adjusting screw 186 bearsagainst the end of a hardened plug 187 in the form carrier, and servesas a means for varying the bracing effect of the brace.

In forming or molding the end portions of shoe uppers where thestifi'ener is made pliable b heat, it is sometimes desirable that theend 0 the upper be subjected to the action of a softening heat duringmolding, suflicient to permit the stiffener to be molded into closeconformation with the form. In the present instance the form may beheated by one or more heat units. In the construction illustrated twosuch heat units 188, Fig. 9, are indicated. These extend into a suitablecavity made in the form and are connected to wires 189 which may beconveniently directed along the form carrier 47.

While the upper is being subjected to the upwiping action of the endband and being laid or stretched about the form under the tensioningaction of the clamps and wipers, the uniformity of the final productdemands that the upper be held from displacement on the form; and one ofthe features of the present invention has this in view. In the presentinstance there is provided an abutment or pad to engage the to orintermediate portion of the toe end of the upper and between which andthe form the upper is held during the operation of conforming the upperto the form. Adjustably mounted in the head portion of the machine frameis an arm 190, Fig. 1, which may be secured in position by a set screw191. The arm 190 carries a casing 192 in which is mounted a plunger 193,Figs. 1 and 11, normally held in an upward position by a spring 194within the casing. the upper end of the spring bearing upon the plunger193, and the lower end resting upon an adjustable sleeve 195, wherebythe action of the spring in transmitting pressure to the plunger 193 maybe varied. The spring 194 may be suitably held in place by a rod 196secured to the plunger 193 and extending loosely through the adjustingmember 195. Turning movement of the plunger is prevented by a lug 197which projects within a slot 198 in the casing, and its upward movementis limited by engagement of a nut on the end of the rod 196 with themember 195.

Pivotally connected to the top of the plunger 193 at 199, Figs. 1 and16, is the rest 200 which carries a pad 201 having a surfacecorresponding to the contour surface of the opposed portion of the form.Springs 202, Fig. 16, normally hold the rest 200 in a predeterminedhorizontal position with provision for tilting movement to conform tothe surface engaged by the pad. The construction is such that theunconfined portion of the upper is depressed by the form into engagementwith the pad 201 which, under the action of the spring 194, assists inpreventing displacement of the upper relatively to the form as the upperis being laid and wiped about the form.

When the upper has been molded about the form, it is permitted to remainin molded position on the form for a considerable length of time toafford an opportunity for the upper to set in the permanent shape it isto have in the finished shoe. If, during this time, the end bandremained in pressing contact with the upper, it would be liable to markthe surface of the upper, due in part to the softened condition of theend stiffener. The present machine provides for relaxing or removing thepressure against the upper while it is permitted to set; and to this endthe mechanism for operating the end band is so constructed and arrangedas to relieve the pressure of the band soon after the upper has beenfully laid about and wiped into conformation with the form, asrepresented in Fig. 1.9.

The machine is further provided with means for trimming the upstandingmarginal flange of the upper about the toe end while the upper is undercontrol of the molding means, to prepare this portion of the upper forthe inseam sewing operation. The trimming means in the constructionshown is associated with the form, and is supported in position to trimthe upper substantially in the plane of the to surface of the Wiperswhen they are in t eir inner position and are holding the upper. Thetrimmer may be variously constructed but in the resent instance it isformed as a blade 203, i s. 7 and 8, carried by a sleeve 204 rotatable aout the stem 176 and supported in such position that the surplus upperstock wiped in by the wipers will be brought into the field of action ofthe trimmer. The sleeve 204 is mounted on the lower end portion of thebushing 179 and is power operated at times for eflecting the trimmingoperation. Mounted upon the bushing 179 above the sleeve 204 of thetrimmer is a pinion 205 which is in operative engagement with a pinion206 mounted on a shaft 207 extending through a suitable hearing formedin the form carrier 47. At its upper end the shaft 207 is rovided with apinion 208 which is engaged by the teeth of a rack 209, Fig. 7,receiving reciprocating movements at the desired times for operating thetrimmer through a train of mechanism operated by a cam on the sleeve 28.In the present instance the rack 209 is connected by a link 210, Fig. 1,to an arm 211 pivotally mounted at 212 upon the form carrier 47.Connected to the arm 211 is a downwardlyextending arm 213 which isconnected by a link 215 to a bell-crank lever 214. The bellcrank lever214 has connected to it at 216 an operating rod 217, the lower endportion of which is adjustably connected to a cam operated arm 218mounted upon the support 54. The arm 218 is provided with a cam followeror roll 219 which travels in a cam groove 220, Fig. 4, formed in theface of the cam wheel 82, the construction being such that the rack 209Will be reciprocated by rotation of the cam to impart to the trimmer itsoperating movements.

Whcn the end of the shoe upper has been molded t the shape which it isto have in the finished shoe. the shoe is to be lasted. During thelasting operation, it is desirable to subject the upper to a lastingpull at the tip line or where the tip is secured to the vamp. Thereforethe trimming means as herein shown is constructed and arranged to make atrimming cut from a point in front of the tip seam at one side of theend of the upper to a point in front of the tip seam at the oppositeside; and since the size, form, and relation of the tip to the vam mayvary in different styles and sizes of s oes, provision is made foradjusting the trimming means to effect its described purpose upon shoeuppers of different sizes and styles. This may be variously effected,but in the present instance the arm 218 for operating the trimmer isprovided with an end ortion having a series of openings 221 to wliichthe lower end of the operating rod 217 may be selectively connected, theeffect being that the trimmer will be given movements of greater or lessamplitude. The point where the trimmer terminates its cutting movementmay thus be varied to correspond to the requirements of difierent stylesand sizes of shoe up ers, as indicated for example by Figs. 24 an 25where the cutting movement of the knife ends at 224 and 226respectively, in front of the tip seam 223. A corresponding variationwith respect to the point (222 or 225) where the knife begins its out atthe opposite side of the upper may be eifected, when necessary, bysubstituting a knife of different length, the machine being soconstructed that different knives ma be readily substituted. The knifeis adapte to trim the upper as required by a single cuttin movement, butt is immediately returned to its starting position, and for furthereffectiveness in making a clean out along the margin of the upper it isprovided with cutting edges on its opposite sides. It will be evidentthat the trimming knife in the construction shown cuts in a single planeand does not sever from the upper the rear ends of the band of wastematerial which it trims ofl' round the toe. This avoids all danger ofclogging or otherwise interfering with the o eration of different partsof the machine by t e accumulation of scrap material. After the u perhas been removed from the machine the and of material which has beentrimmed off round the toe may be severed from the upper by the use of ahand knife or by other convenient means.

The upper stock will vary in thickness, and since the trimmer is to trimthe upstanding flange of the upper in the plane of the upper surface ofthe wipers, means are provide to insure that the trimmer will operate totrim the stock in the desired relation to the wipers, regardless ofvariations in the thickness of the stock and consequent variations inthe position of the form after the upper has been wiped in by the wipersand after the form has been pressed yieldingly upward. In the presentinstance the sleeve portion 204 of the trimmer is provided with acircular groove 227, Figs. 7 and 8, which is embraced by an arm 228removably secured in a head 229 on the end of a carrler 230, Figs. 1 and7, mounted on the pivotal support 46 of the form carrier at 231. Thehead 229 is'connected to a stem 232, Fig. 7, which extends upwardlythrough the form carrier with a sliding lit, suitable stops such as nuts233 bein provided to adjustably limit the downwar movement of the head229 under the action of a spring 234 interposed between the carrier 47and the top portion of the head 229. Mounted in the cover plate 61 whichoverlies the wiper holders 62 is an adjustable stop 235 which is adaptedto be en aged by a lug 236 carried by the head 229 w en the form carrier47 is moved downwardly to lay the upper about the form. The constructionis sac that when the form and the wipers are relativel moved to lay theupper about the form an to compress its marginal portion between theform and the wipers, the cutting plane of the trimmer is automaticallydetermined irrespective of the position of the form.

In order to ermit the trimmer to be readily removed w ien desired, thearm 228, Fig. 7, is made detachable from its connection with the trimmerby means of a spring clip 237. Upon lifting the clip 237, the arm 228may be moved backwardly 111 the head 229 and disengaged from thetrimmer, whereupon the thumb nut 178 may be loosened to permitdetachment of the form and subsequent removal of the trimmer.

W'hen the end of a shoe u per has been formed and trimmed, as hereinefore indicated, it is liable to stick or adhere to the form after theupper has set; and to meet this condi tion the present inventionprovides for detaching the finally shaped and molded end of the upperfrom the form. In the present instance a detacher is provided,consisting of a stem or plunger 238, Figs. 8 and 9, having a headedportion 239 normally held retracted in a slot formed in the end portionof the form by means of a spring 240 interposed between the surface 185of the form and a. head 241 on the plunger, the construction being suchthat after the end of the upper has been molded and set to the form andthe form has been moved to its inoperative position, a push upon thehead 241 of the plunger will serve to move the molded end of the shoeupper endwise of and detach it from the form. To avoid interference withthe lower end of the stem 176 which co-operates to hold the form on theform carrier, the lower end portion of the stem 176 is slotted from itsbottom surface upward and the stem or plunger 238 extends through suchslotted portion.

A shoe upper formed in accordance with the resent disclosure and adaptedmore particu arly for welt shoes, is shown in Fig. 26, wherein it willbe seen that the toe end of the upper is molded or formed to the finalshape it is to have in the finished shoe, and is provided with anupwardly extending marginal flange 243 of a height substantiallycorresponding to the height of the lip of the insole to which it is tobe attached. the trimmed portion of the flange terminating preferably atpoints in front of the tip line to provide adjacent to the tip line theextensions 244 for use during the lasting operation. The flange 243 asthus molded is in position to lie in close conformity to the rib of thecorresponding shoe insole and extends upwardly from a portion which ismolded over the surface 171 of the form to lie on the feather of theinsole.

In the use of the machine shown, the workman positions the invertedupper on the presenter by engaging the end portions of the presenterwith the jig holes in the upper, as shown in Fig. 23, and then moves thepresenter to carry the upper into operative relation to the form. Indoing this he moves the pins on the presenter into the slots 85 in thewipers until the pins interlock with the otl'set portions 94 of theslots, and when the presenter has finally reached the position thuspredetermined by the positioning slots in the wipers, the shoe upperassumes a predetermined posit-ion relatively to "the form. Thiscondition is represented in Fig. 11, at which time it will be noted thatthe clamps 96 are in their raised or open position. The workmanthereupon treadles the machine, the first efiect of.which is that theclamps de scend and engage the marginal portion of the upper and pressit yieldingly against the top surface of the wipers, and at the sametime press downwardly upon the holding pins of the presenter and assisttheoperator in effecting its detachment from the upper,

the ends of the pins being preferably somewhat rounded to permit them toslip out readily when they are pushed down. The upper is then ositionedin the machine and held in its prec etermined relation to the formbetween the clamps and the wipers. During the'downward movementof theclamps, the links 103 move them also inwardly to bring their edgeportions in close proximity to the edge portions of the wipers,substantially as re iresentedin Fig. 13. The end band is at this time inits closed position, ready to act with wiping pressure upon the uppertoward the bottom 0 the form. The form thereupon is moved downwardlyupon the unconfined portions of the end of the upper and the toe pad201-engages and holds the upper from displacement about the form. As theform continues to descend, the marginal portions of the upper arepartially withdrawn from the confining means or clamps, the upper islaid about. the form with an upper stretching pull, and the end bandsimultaneously acts towipe or work the upper heightwisc about the end ofthe form, substantially as indicated in Fig. 16. The downward movementof the form is continued until the shouldered portion 171 of the form isslightly below the lower surface of the wipers, whereupon the wi persare automatically moved inwardly to gather and lay the upper over thebottom of the form and-to mold it into an upstanding flange against theshoulder 1T2. Prior to anysuhstuntiul inward movement of the wipers theclamps areautomaticallyoperated to relieve the nuu'gii'ial port ions ofthe upper from clnn'iping pressure. substantially as indicated in Fig.17. After the wipers have wiped in the marginal portions of the upper.and while the upper is still held between the form and the rest. 201 andsubjected to the pressnre of the end hand, the form isslightly raisedunder the action of the spring 58, Fig.

'1. to rcss the u )er firmly against the bot tom surface of tie wipers.whereupon the a plurality of jig trimmer is' automatically operated totrim of time to permit the u per to set to the final shape it is to havein t to finished shoe, during which time an upper may have beenpresentedand molded in the other portion of the machine, the workmanagain treadles that. part of the machine in which the first upper wasmolded, whereupon the .wipers move out wardly and the formriScs'carPying the end of the shoe upper, which may be detached fromtheform by the detacher. Justprior to the conelusionof the second ortion ofthe cycle of operations,the end ban is moted inwardly so that atthebeginning of another operation-for molding the end'of a shoe upperthe band willbe in position to effect its upwiping and rubbin pressureupon the upper.
